Is a signature added this way legally binding?

In many jurisdictions — including under the US ESIGN Act and the EU's eIDAS regulation — an electronic signature applied with clear intent is generally enforceable for everyday agreements. High-value or regulated contracts may require a qualified digital certificate, which is a different mechanism. If the stakes are significant, check with a lawyer rather than relying on a converter's FAQ.

Does my signature image get uploaded?

No. It is drawn on a canvas in your browser and stamped into the PDF locally. Nothing about your signature is transmitted or stored.

Is Sign PDF really free?

Yes — every tool on PDF Love is free, with no account, no email, no trial period, and no watermark stamped on your output. There is no file-count limit and no daily quota.

What happens to my files?

They never leave your device. This tool runs entirely inside your browser using WebAssembly, so your file is read from local memory, processed locally, and handed straight back. Nothing is uploaded, which is why it still works with your Wi-Fi switched off.

Is there a file size limit?

There is no limit imposed by us. Because the work happens on your own device, the practical ceiling is your available memory — comfortably a few hundred megabytes on a normal laptop or phone.

Does it work on a phone or tablet?

Yes. The site is built mobile-first and works in any modern browser on iOS, Android, Windows, macOS, and Linux. There is nothing to install.
